Abstract
224,893. British Thomson-Houston Co., Ltd., (Assignees of Compagnie Francaise pour l'Exploitation des ProcÚdÚs Thomson-Houston). Nov. 16, 1923. [Convention date]. Void [Published under Sect. 91 of the Act]. Alternating-current motors.-The speed and power factor of an induction motor are regulated by cascading with a salient-pole polyphase commutator machine, such as a Scherbius motor, he commutator machine being excited bv a frequency-changer from which the excitation current is taken at angularly displaceable brushcarriers, the frequency-changer being also connected through slip-rings to the mains.
